TRUSS-PAD.

TSPEGIEICATION forming part of Letters Patent No. 341,176, dated May 4, 1886.

Application filed November 19,1885. Serial No.183,3-l1. (No model.)

To aZZ whom it may concern.-

Be it known that I, ALONZO D. SMITH, of New \Voodstock, in the county of Madison and State of New York, have invented a new and useful Improvement in Truss-Pads, of which the following is a specification, reference being had to the annexed drawings, forming a part thereof, in which" Figure 1 is a side elevation. Fig. 2 is a transverse section taken on line a: x in Fig. 1. Fig. 3 is a rear elevation.

Similar letters of reference indicate corresponding parts in the different figures of the drawings.

The object of my invention is to provide a truss-pad for the prevention of intestinal protrusion through any of the abdominal walls.

My invention consists of the construction and arrangement of parts, as will be hereinafter fully described and claimed.

Thelarger pad, A, is formed of wood or other suit-able material, with an outwardly-convex face, a, and with a central aperture, b. A convex metallic plate, B, provided with a short cylindrical stem, 0, is secured to the back of the pad A by means of ordinary steel screws, or in any other suitable way.

In the aperture b of the pad A is inserted the hollow cylindrical stem 0, having upon its outer end the pad D. The pad D is smaller in diameter than the pad A, and its face is made outwardly convex.

\Vithin the hollow stem 0 is placed a rubber spring, E, having formed on the opposite ends thereof flanges d d, the flange d closely fitting the interior of the hollow stem 0, and the flange d closely fitting the aperture b of the pad A and abutting upon the back plate, B, so that the rubber spring E not only acts as a yielding support for the smaller pad,B, but it also forms an efficient connector for holding the two pads A B in proper relation to each other. The stem 0 of the pad D fits the aperture b of the pad A closely, so that the pad D may move in or out without lateral movement.

WVhen applied to the patient, the smaller pad, D, is arranged opposite the hernial opening, while the larger pad, A, supports the abdominal walls around the opening.

The stem 0 is provided with a transverse opening for receiving the end of the wire F, which surrounds the body of the wearer of the truss, and the truss'pad is held in any desired position upon the wire by a binding-screw, f, which is fitted in the stem 0 and bears upon the side of the wire F.

' Although Ihave described the spring employed in my improved truss-pad as being made of rubber, Ido not limit or confine myself to the use of a rubber spring, asametallic spring of substantially the same form might be substituted therefor.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a trusspad, the combination, with the centrally-apertured pad A, of a smaller pad, D, provided with a tubular stem, G, closely fitted to the aperture of the pad A, and a spring, E, having flanged ends, and arranged to connect the smaller and larger pads, substantially as herein specified.
